SHOP CASE KNIVESThe Viper Orso Orange G-10 is a premium folding knife built for everyday carry, designed by Jens Ansø and handcrafted in Maniago, Italy. Blending modern design with practical function, the Orso delivers high-end materials, ergonomic construction, and smooth mechanical action in a slim, rugged form.
Its 3.40-inch drop point blade is made from Böhler M390 stainless steel, widely regarded as one of the best knife steels available. The stonewashed finish adds wear resistance while maintaining a clean, low-reflective surface. A crowned spine adds a level of refinement and enhances comfort during extended use. Thanks to M390’s superior edge retention, corrosion resistance, and hardness, this knife is built to cut efficiently and hold up in challenging conditions.
The blade deploys using a low-profile flipper tab that works in tandem with a thrust-bearing pivot system. This setup provides fast, fluid one-handed opening with minimal effort. The blade locks in place with an inset stainless steel liner lock, giving it the reliability and strength needed for daily tasks without unnecessary bulk.
The handle features textured orange G-10 scales for improved grip, even in wet or gloved hands. The G-10 overlays durable stainless liners and is backed by a titanium backspacer that keeps the build strong and lightweight. Ergonomic shaping and subtle contouring ensure the knife feels balanced and secure in hand, making it comfortable for long periods of use.
At 4.50 inches closed and 8.12 inches overall, the Orso fits comfortably in a pocket while offering a full-size grip in use. Weighing only 3.20 ounces, it's easy to carry all day. The titanium tip-up pocket clip allows secure right-hand carry, and a lanyard hole in the backspacer provides added carry options.
Whether you're looking for a reliable EDC or a finely crafted folder that reflects both performance and style, the Viper Orso Orange G-10 stands out with precision fit, premium components, and no-nonsense design from one of the most respected names in modern knifemaking.
